LP298XS Datasheet – Low Dropout Regulator With Shutdown
100-mA Ultra-Low Dropout Regulators With Shutdown
LP298XS overview
The LP298XS is a 100-mA Ultra-Low Dropout Regulators With Shutdown made by Texas Instruments, supplied in an SOT-23 5Pin Type package. The absolute maximum ratings table on this page lists the 11 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the LP298XS pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The LP2980 is a 50 mA, fixed-output voltage regulator de- signed specifically to meet the requirements of battery- powered applications.
Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2980 delivers unequaled performance in all specifications critical to battery-powered designs:
Dropout Voltage. Typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load. Ground Pin Current. Typically 375 µA @ 50 mA load, and 80 µA @ 1 mA load. Sleep Mode. Less than 1 µA quiescent current when ON/ OFF pin is pulled low.
Smallest Possible Size. SOT-23 and micro SMD packages use an absolute minimum board space. Minimum Part Count. Requires only 1 µF of external capacitance on the regulator output. Precision Output. 0.5% tolerance output voltages available (A grade).
5.0V, 3.3V, and 3.0V versions available as standard products.
